Problems solved by technology

At present, the flue-cured tobacco seedling production mainly adopts the floating seedling cultivation method. The nutrients required for the existing floating seedling cultivation mainly come from the nutrients provided by chemical fertilizers. The production of organic tobacco leaves requires that no chemical fertilizers be applied from the beginning of seedling cultivation. Therefore, the tobacco seedlings provided by conventional floating seedling cultivation technology Cannot meet the requirements of organic tobacco leaf production
At the same time, the existing seedlings mainly use peat or peat as the substrate, which has a problem of high soluble salt content. Because the soluble salt content in the substrate fertilizer is too high, it may not only form reverse osmosis pressure, but also replace the water in the root system of the seedlings. come out, causing the root tip of the plant seedlings to turn brown or dry, the root system of the plant is damaged, unable to absorb water and nutrients, causing the seedlings to appear wilting, yellowing, tissue necrosis or plant shortness; and the soluble salt content in the base fertilizer is too high. Increase the incidence of root rot caused by the cotton rot fungus and reduce the growth rate of seedlings

Embodiment 1

[0023] Example 1: Take 70 parts of vermicompost, 70 parts of biogas residue, and 30 parts of perlite according to the volume ratio, mix and stir evenly, and then put them in a wooden floating tray with 10 × 16 holes, fill them up and compact them, and sow two grains in each hole Put the flue-cured tobacco seeds into the nursery ponds filled with clean water, the volume is cubic centimeters, add biogas slurry to the nursery ponds 30 days, 40 days, and 50 days after sowing, and the amount of biogas slurry used is 5 kg / pan each time That's it.

Embodiment 2

[0024] Example 2: Take 30 parts of vermicompost, 30 parts of biogas residue, and 10 parts of perlite according to the volume ratio, mix and stir evenly, and then put them in a wooden floating tray with 10 × 16 holes, fill them up and compact them, and sow two grains in each hole Put the flue-cured tobacco seeds into the seedling pond filled with clean water. The portion is cubic centimeters. Add biogas slurry to the seedling pond on the first day after sowing.

Embodiment 3

[0025] Example 3: Take 80 parts of vermicompost, 80 parts of biogas residue, and 40 parts of perlite according to the volume ratio, mix and stir evenly, and put them in a wooden floating tray with 10 × 16 holes, fill them up and compact them, and sow two grains in each hole Put the flue-cured tobacco seeds into the seedling ponds filled with clean water, the portion is cubic centimeters, and add biogas slurry to the seedling ponds on the 1st day, 10th day, 20th day, 30th day, 40th day, 50th day, and 60th day after sowing , The amount of biogas slurry used can be calculated according to 10 kg / pan each time.

Abstract

The invention discloses an organic tobacco seedling culture method, which comprises the following steps that: an organic seedling culture substrate is put into a wooden floating plate, filled and compacted, added with seeds, and put into a seedling culture pond with clean water; organic nutrient solution is applied into the seedling culture pond for 1 to 7 times within 1 to 60 days after sowing, and 1 to 10kg / plate of solution is applied every time. The method not only has high emergence rate but also has very stable emergence rate so that the cultured tobacco seedlings also meet the standards of conventional strong seedlings, provide organic tobacco seedlings for production, can meet the needs for the seedlings for organic tobacco production, and has abnormally significant effect. Many times and may periods of tests have proven that the tobacco seedlings produced by the method have the significant effect of resisting draught and cold and promoting root development, and can improve the emergence rate and the disease resistance of seedlings. Therefore, the organic tobacco seedling culture method has very good popularization value.

Description

technical field [0001] The invention relates to a method for raising seedlings of tobacco seedlings, in particular to a method for raising seedlings of organic tobacco seedlings. Background technique [0002] In the production of organic tobacco leaves, the whole production process must meet the production standards of organic tobacco leaves, except that the place of origin meets the certification standards of organic production places. Among them, cultivating organic flue-cured tobacco seedlings is the primary link in the production of organic tobacco leaves. At present, the flue-cured tobacco seedling production mainly adopts the floating seedling cultivation method. The nutrients required for the existing floating seedling cultivation mainly come from the nutrients provided by chemical fertilizers. The production of organic tobacco leaves requires that no chemical fertilizers be applied from the beginning of seedling cultivation. Therefore, the tobacco seedlings provided ...
